Oxalate is a nonessential metabolite in mammals that must be excreted or sequestered to maintain homeostasis. Normal adults excrete oxalate in urine ranging from 28 to 43 mg/day (311–478 μM/day), with the average excretion being slightly higher in men than in women (Asplin and Coe, 2007...

Increasing the concentration of urate promotes the crystallization of calcium oxalate in human urine. In this study the possibility that this effect might be attributable to the attenuation of the inhibitory activity of urinary glycosaminoglycans (GAGs) was explored. Urine sample were collected from 20...

Centrifuged and filtered urine is often used to evaluate in vitro the crystallization processes of calcium oxalate (CaOx), but even such simple manipulations can alter the composition of the urine, as regards its protein and lipid concentrations. In urine samples taken from 17 normal male adults,...
Abstract Estimation of urinary supersaturation with calcium oxalate (CaOx) is a valuable tool in urolithiasis investigations. Methods used to assess supersaturation are usually empirical or dependent on a complete ionic analysis of the urine for computation of the supersaturation ratio. EQUIL21requires an...
Idiopathic calcium oxalate nephrolithiasis is a highly recurrent disease that is increasing in prevalence. Decades of research have not identified effective methods to consistently prevent the formation of nephroliths or induce medical dissolution. Idiopathic calcium oxalate nephroliths form in association ...
We have studied the kinetics of oxalate-induced turbidity in fresh human urine and artificial urine. Assays are performed in 96-well plates, which allows many oxalate concentrations to be studied, repeatedly, in a short time. The metastable limit is defined in terms of the lowest oxalate concent...
Calcium oxalate crystals in urine What does it mean to have calcium oxalate crystals in urine? It could indicate that the patient is suffering from nephrolithiasis and acute renal failure. Although, calcium oxalate crystals is present in the urine of people with high dietary oxalate ingestion and ...
